I live in Lincoln county Oklahoma , the old Katy railroad went through Tryon and they used the rock for riprap at most of the drainages that went under the tracks . Was wondering where they may have gotten it , a lot of it is fractured but I've been able to get some good flakes from them .
I'm going to try and cook some of it when I get set up for it , I have a big fire ring and can go to the river for some sand , I'll use a cut off drum to treat it in.
